Power efficient reliable routing protocol for mobile ad-hoc networks

Mobile ad-hoc networks have certain constraints, including power shortages and an unstable wireless environment, more power-efficient routing protocols are needed. Accordingly, this paper propose a new routing protocol, PERRA (power efficient reliable routing protocol for mobile ad-hoc networks), which uses a new cost function to select the optimum path based on considering the minimum residual energy of the nodes on a path, the total energy consumed by a path to transmit and process a packet, and the path´s stability in accordance with the node mobility. As a result, the proposed method increases the power efficiency and decreases the route-reconstructions due to residual power shortages and node mobility.
